Not built in, but ES6 does provide a better story for this using 
generators and for-of:

```js
// using a generator function
function* entries(obj) {
   for (let key of Object.keys(obj)) {
     yield [key, obj[key]];
   }
}

// an alternative version using a generator expression
function entries(obj) {
   return (for (key of Object.keys(obj)) [key, obj[key]]);
}

for (let [key, value] of entries(myObj)) {
   // do something with key|value
}
```

for (let [key, value] of entries(myObj)) {
